In a master/slave DNS architecture, what is the role of the slave server?

It only caches responses for clients and never serves authoritative data

It obtains a read-only copy of the zone from the master and serves it authoritatively

It holds the master copy of the zone and pushes updates to other servers

It forwards all queries to the master without answering them locally

A zone has a large number of records, and the administrator wants to minimize the bandwidth consumed during routine updates. The master and slave are both BIG-IP DNS systems, and the slave already has a current copy of the zone. Which approach will best achieve this goal?

Enable IXFR so only changed records are transferred

Disable NOTIFY and rely on the refresh timer

Configure the zone as static on the slave

What is the primary benefit of DNSExpress in BIG-IP DNS?

It accelerates zone transfers by using a more efficient synchronization mechanism

It encrypts all DNS queries between clients and servers

It caches zone data on client devices to reduce server load

It replaces the need for SOA timers entirely

A new slave server is being added to an existing DNS infrastructure to serve as an authoritative server for a zone that has been running for years. The slave has no prior copy of the zone. What type of zone transfer will the slave perform to obtain the zone for the first time?

Incremental zone transfer (IXFR)

Which protocol is used to transfer zone data between authoritative DNS servers?

DNS zone transfer (AXFR/IXFR) over TCP

Simple Mail Transfer Protocol (SMTP)
